Fig. 22 is a section analogous to Fig. 19 with opaque spacer plates arranged between the prisms so that the rays of light from the prisms Will not intermingle until after they have passed beyond the prism frame.

I provide a main skeleton frame 10 in the form of a bill-board supported upon posts 11 and back-braces 12, and preferably the front part of the bill-board is made up of a plurality of rectangular plates secured together as illustrated in the application hereinbefore referred to, or if desired the front can be made up of transparent panels 13 that are removable from the frame and interchangeable, as also illustrated in the prior application referred to. Preferably the panels 13 are transparent and have the pictorial advertising placed on their front faces in natural colors when displaying pictures and the like, and back of these panels is a demountable prism frame 14 in which aplurality of colored multiform prisms 15 are secured in osition to throw a flood of colored lights on t 1e rear of the panels 13 to illumi1 nate the advertising. A lamp 16, having a reflector l?, is arranged rearwardly of the prism frame 14.

As shown in Figs. 7 to inclusive, the prism frame is constructed as follows I provide end plates 19 and 20 with al cross plate 21 to Which the side plates 22 and intermediate plates 23 are detachably secured as shown. The end plates have overlapping corner slots 24 and corner extensions 25 that are arranged at right angles to the plates 19 and 20 and these extensions have recesses 26 into which the detents 27 of the side plates 22 are extended and detachably secured.

These end plates have detents 28 extending into recesses in the ends of the intermediate plates in a manner similar to the connection of the corner portions of the side plates. In ether Words, the end plates have detents 28 that are fitted info the recesses 30 of end flanges 81 that are integral with the intermediate plates 2?. The intermediate plates 23 are spaced apart from one another and also from the side plates so as to form elongated slots 32 between their flanges 33-34 on which the prisms 15 are seated when arranged in the elongated channels 35 between the plates.

The prism frame when assembled is made of suitable size to cover a pictorial advertising that is a miniature reproduction of the advertising to be placed on the face of the bill-board, as illustrated in Fig. 3, In this ligure it is assumed that the prism frame is laid down over a small picture having land and trees in the foreground, an island in the bay, and mountains and a steam vessel in the distance, this picture being assumed to be placed on the face of Fig. 1 .vhenputin use; aud when the prism frame is placed over this miniature picture the multiform prisms 15 can be placed and secured in the channels 35 to reproduce in colors the picture shown in Fig. 3, so that when the prism frame is filled with the prisms and placed before thelamp 16 in Fig. 2, the colors of this picture will be projected to and through the transparent' panels to illuminate the advertising in colors.

It is understood that this frame can be placed in front of the bill-board and the flood of colors thrown on the advertising from that position. Preferably the multiform prisms 15 are fornied of broken pieces of transparent glass of various colors, but can be formed of broken pieces of transparent quartz and semi-precious stones.

The glass and stones are broken to give them a ragged exterior at the sides and ends so that When light is directed through them it will spread out in a floodY of prismatic colors of great brilliancy as illustrated diagrammatically in Fig. 4. As seen therein there are six multiform prisms grouped together, having the colors of red, orange, blue, violet, yellow and green, each stone having a ragged prismatic exterior that causes the rays of light from the lamp 16 to blend in a flood of dazzling color.

Preferably these multiform prisms are secured in the prism frame as illustrated in Fig. 18, thatis, the prisms are arranged eentrally over the slots 32 and are secured in that position by spring plates 37 so that when the frame is supported in front of the lamp 16 the prisms will be secured on the slots so the light Will be directed centrally through the prisms to illuminate the bill-board, stage or the like.

It is understood that any suitable means may be employed in securing the prisms in the frame. If desired. the prisms can be separat-ed from one another by opaque plates 38, as illustrated in Fig. 22, and when such plates are used, the lights through the prisms do not blend until after they have passed beyond the outer surface of the frame. It desired the multifcrm colored prisms can be arranged directly in the bill-board panels 13, as illustrated in igs. 6 and 7.

In Fig. 6 it is assumed that the letter O in the word Panoram7 shown in Fig. 1, is formed oi multitorm prisms that are set in the face of the panel 13. In other words, I secure angle irons 39-4O to the back of a panel 13 around an opening through the panel in the form or" a large letter O, and in the space between these irons I lill with the prisms 15 and arrange a lamp 16 nea-r them so that it will direct light through the prism 15 to illuminate the letter. It is understood that all of the letters can be so formed if desired, t is also understood that this form oi' arranging the multiiorm prisms can be adapted to emphasize or beautify anything placed on a bill-board, such, for instance, as imitating diamonds worn as a necklace, or a ring on the linger of a beautiful lady, if pictured on the bill-board, or can be used for other artistic purposes.

In operation the apparatus is used as described.

I claim as my invention:

1. In a multiform prism advertising apparatus the combination with a main skeleton bill-board frame, panels therein having pictorial advertising thereon, of a lamp for illuminating the advertising on said panel, a demountable prism frame in said main trame and multi'form prisms of diii'erent colors grouped together and interposed between said lamp and panel for the purpose specified.
